Method Detail

getParent

public FunctionMapper getParent()

Returns the parent mapper, or null if no parent.

setParent

public void setParent(FunctionMapper parent)

Sets the parent mapper.

Parameters:

parent - the parent mapper, or null if no parent.

resolveFunction

public Function resolveFunction(java.lang.String prefix,
                                java.lang.String name)

Description copied from interface: FunctionMapper

Resolves a function Function with the specified name and prefix.

Note: not all EL evaluator support FunctionMapper.resolveFunction(java.lang.String, java.lang.String). Currently only JSP 2.0/2.1 EL-based expression factories support this method. You can check ExpressionFactory.isSupported(int) for this support.

Specified by:

resolveFunction in interface FunctionMapper

Overrides:

resolveFunction in class TaglibMapper

Parameters:

prefix - the prefix of the function, or "" if no prefix

name - the name of the function to resolve

getClassNames

public java.util.Collection<java.lang.String> getClassNames()

Description copied from interface: FunctionMapperExt

Returns a readonly collection of the logic names of the class (never null). Note: it is the name to resolve class, not the real class name. In other words, it is the logical name maintained by this function mapper.

Specified by:

getClassNames in interface FunctionMapperExt

Overrides:

getClassNames in class TaglibMapper

resolveClass

public java.lang.Class resolveClass(java.lang.String name)

Description copied from interface: FunctionMapperExt

Resolves a class with the specified logic name, or null if not found.

Note: not all EL evaluator support FunctionMapperExt.resolveClass(java.lang.String). JSP 2.0/2.1 EL-based expression factories don't support this method. You can check ExpressionFactory.isSupported(int) for this support.

Specified by:

resolveClass in interface FunctionMapperExt

Overrides:

resolveClass in class TaglibMapper

Returns:

the class of the specified logic name.
