| StylesheetCache | | public class StylesheetCache (Code) | | XSL File Cache
This class keeps a master copy in memory of each XSL Stylesheet file.
When a Transformer object is requested a copy of the master Stylesheet is
done. This is faster than re-loading de XSL file from disk.
StylesheetCache is a WeakHashMap so cached stylesheets can be automatically
garbage collected is memory runs low.

it with loading date for cached objects. | | public static void | setParameters(Transformer oXSL, Properties oProps)
Set parameters for a StyleSheet taken from a properties collection.
This method is primarily designed for setting environment parameters.
Parameters:
oXSL - Transformer object.
Parameters:
oProps - Properties to be set as parameters. | | public static void | transform(String sStyleSheetPath, InputStream oXMLInputStream, OutputStream oOutputStream, Properties oProps)
Perform XSLT transformation
Parameters:
sStyleSheetPath - File Path to XSL style sheet file
Parameters:
oXMLInputStream - Input Stream for XML source data
Parameters:
oOutputStream - Stream where output is to be written
Parameters:
oProps - Parameters for Transformer. | | public static String | transform(String sStyleSheetPath, String sXMLInput, Properties oProps)
Perform XSLT transformation
Parameters:
sStyleSheetPath - File Path to XSL style sheet file
Parameters:
sXMLInput - Input String with XML source data

oProps - Parameters for Transformer. |
| setParameters | | public static void setParameters(Transformer oXSL, Properties oProps) throws NullPointerException(Code) | | Set parameters for a StyleSheet taken from a properties collection.
This method is primarily designed for setting environment parameters.
Parameters:
oXSL - Transformer object.
Parameters:
oProps - Properties to be set as parameters. The substring "param_"will be added as a preffix to each property name passed as parameter.So if you pass a property named "workarea" it must be retrieved from XSLas <xsl:param name="param_workarea"/>
throws:
NullPointerException - if oXSL is null or oProps is null |
