This class provides also some methods for mapping SampleDimensionType to DataBuffer types. since:    2.1 version:    $Id: TypeMap.java 25972 2007-06-21 13:38:35Z desruisseaux $ author:    Martin Desruisseaux Method Summary public static  ColorInterpretation getColorInterpretation(ColorModel model, int band)      Returns the color interpretation code for the specified color model and band number. Parameters:   model - The color model. Parameters:   band - The band to query. public static  int getDataBufferType(SampleDimensionType type)      Returns the DataBuffer type. public static  InternationalString getName(SampleDimensionType type)      Returns the sample dimension type name as an international string. public static  NumberRange getPositiveRange(SampleDimensionType type)      Returns the range of positive sample values (excluding 0). public static  NumberRange getRange(SampleDimensionType type)      Returns the full range of sample values for the specified dimension type. public static  SampleDimensionType getSampleDimensionType(Range range)      Returns the smallest sample dimension type capable to hold the specified range of values. Parameters:   range - The range of values. public static  SampleDimensionType getSampleDimensionType(double min, double max)      Returns the smallest sample dimension type capable to hold the specified range of values. An heuristic approach is used for non-integer values. Parameters:   min - The lower value, inclusive. Parameters:   max - The upper value, inclusive as well. public static  SampleDimensionType getSampleDimensionType(long min, long max)      Returns the smallest sample dimension type capable to hold the specified range of values. Parameters:   min - The lower value, inclusive. Parameters:   max - The upper value, inclusive as well. public static  SampleDimensionType getSampleDimensionType(SampleModel model, int band)      Returns the sample dimension type for the specified sample model and band number. public static  int getSize(SampleDimensionType type)      Returns the size in bits. public static  boolean isFloatingPoint(SampleDimensionType type)      Returns true for floating-point data type. public static  boolean isSigned(SampleDimensionType type)      Returns true for signed sample type. public static  Number wrapSample(double value, SampleDimensionType type, boolean allowWidening)      Wraps the specified value into a number of the specified data type. Method Detail getColorInterpretation public static ColorInterpretation getColorInterpretation(ColorModel model, int band) throws IllegalArgumentException(Code) Returns the color interpretation code for the specified color model and band number. Parameters:   model - The color model. Parameters:   band - The band to query. The code for the specified color model and band number. throws:   IllegalArgumentException - if the band number is not in the valid range. getDataBufferType public static int getDataBufferType(SampleDimensionType type)(Code) Returns the DataBuffer type. This is one of the following constants: DataBuffer.TYPE_BYTE TYPE_BYTE , DataBuffer.TYPE_USHORT TYPE_USHORT , DataBuffer.TYPE_SHORT TYPE_SHORT , DataBuffer.TYPE_INT TYPE_INT , DataBuffer.TYPE_FLOAT TYPE_FLOAT , DataBuffer.TYPE_DOUBLE TYPE_DOUBLE or DataBuffer.TYPE_UNDEFINED if the type is unrecognized. getName public static InternationalString getName(SampleDimensionType type)(Code) Returns the sample dimension type name as an international string. For example, the localized name for SampleDimensionType.UNSIGNED_16BITS is "16 bits unsigned integer" in English and "Entier non-signé sur 16 bits" in French. getPositiveRange public static NumberRange getPositiveRange(SampleDimensionType type)(Code) Returns the range of positive sample values (excluding 0). This range is non-null only for unsigned type. A range excluding 0 is sometime usefull when the 0 value is reserved for a "no data" category. getRange public static NumberRange getRange(SampleDimensionType type)(Code) Returns the full range of sample values for the specified dimension type. getSampleDimensionType public static SampleDimensionType getSampleDimensionType(Range range)(Code) Returns the smallest sample dimension type capable to hold the specified range of values. Parameters:   range - The range of values. The smallest sample dimension type for the specified range. getSampleDimensionType public static SampleDimensionType getSampleDimensionType(double min, double max)(Code) Returns the smallest sample dimension type capable to hold the specified range of values. An heuristic approach is used for non-integer values. Parameters:   min - The lower value, inclusive. Parameters:   max - The upper value, inclusive as well. The smallest sample dimension type for the specified range. getSampleDimensionType public static SampleDimensionType getSampleDimensionType(long min, long max)(Code) Returns the smallest sample dimension type capable to hold the specified range of values. Parameters:   min - The lower value, inclusive. Parameters:   max - The upper value, inclusive as well. The smallest sample dimension type for the specified range. getSampleDimensionType public static SampleDimensionType getSampleDimensionType(SampleModel model, int band) throws IllegalArgumentException(Code) Returns the sample dimension type for the specified sample model and band number. If the sample model use an undefined data type, then this method returns null . Parameters:   model - The sample model. Parameters:   band - The band to query. The sample dimension type for the specified sample model and band number. throws:   IllegalArgumentException - if the band number is not in the valid range. getSize public static int getSize(SampleDimensionType type)(Code) Returns the size in bits. The value range from 1 to 64. This is similar, but different than DataBuffer.getDataTypeSize , which have values ranging from 8 to 64. isFloatingPoint public static boolean isFloatingPoint(SampleDimensionType type)(Code) Returns true for floating-point data type. isSigned public static boolean isSigned(SampleDimensionType type)(Code) Returns true for signed sample type. wrapSample public static Number wrapSample(double value, SampleDimensionType type, boolean allowWidening) throws IllegalArgumentException(Code) Wraps the specified value into a number of the specified data type. If the value can't fit in the specified type, then a wider type is choosen unless allowWidening is false . Parameters:   value - The value to wrap in a Number object. Parameters:   type - A constant from the SampleDimensionType code list. Parameters:   allowWidening - true if this method is allowed to returnsa wider type than the usual one for the specified type . The value as a Number. throws:   IllegalArgumentException - if type is not a recognized constant. throws:   IllegalArgumentException - if allowWidening is false and the specified value can't fit in the specified sample type.
