Method Detail

convert

public static String convert(Object value)(Code)

Convert the specified value into a String.

For more details see ConvertUtilsBean.

Parameters:
value - Value to be converted (may be null) The converted String value
See Also: ConvertUtilsBean.convert(Object)

convert

public static Object convert(String value, Class clazz)(Code)

Convert the specified value to an object of the specified class (if possible). Otherwise, return a String representation of the value.

For more details see ConvertUtilsBean.

Parameters:
  value - Value to be converted (may be null)
Parameters:
  clazz - Java class to be converted to The converted value
See Also:   ConvertUtilsBean.convert(StringClass)

convert

public static Object convert(String[] values, Class clazz)(Code)

Convert an array of specified values to an array of objects of the specified class (if possible).

For more details see ConvertUtilsBean.

Parameters:
  values - Array of values to be converted
Parameters:
  clazz - Java array or element class to be converted to The converted value
See Also:   ConvertUtilsBean.convert(String[]Class)

convert
public static Object convert(Object value, Class targetType)(Code)
