Method Detail

process

public String process(String sMacro,
                      ParameterResolver resolver,
                      int cDepth)

Process macro parameter expansion on sMacro containing no registered delimiters.

Parameters:

sMacro - a string starting with prefix and ending with suffix

resolver - macro parameter ParameterResolver

cDepth - expansion depth

Returns:

expanded macro parameter or emptry string if macro parameter evaluates to null

canProcess

public boolean canProcess(String sMacro)

Return true iff sMacro contains the delimiter that this processor handles.

Parameters:

sMacro - the macro parameter

Returns:

true iff this processor can process sMacro

getDelimiter

public String getDelimiter()

Return delimiter being used by the processor.

Returns:

delimiter used by the processor or empty string if processor does not have a delimiter

validateMacroExpansion

public boolean validateMacroExpansion(String sProp,
                                      String sPropValue,
                                      String sDefault,
                                      int cDepth)

Validate macro expansion is not self referencing or contain circular references that will never complete expansion.

Parameters:

sProp - the property

sPropValue - the expanded property value

cDepth - count of macro expansions

Returns:

false if self referencing in macro expansion or exceed {#link #MAX_MACRO_EXPANSIONS}; otherwise return true
