ProductionProcessor
public ProductionProcessor(ProductionProcessor[] production,
java.lang.String type,
java.lang.Object[] parameters)
throws java.lang.Exception
- Constructs a new ProductionProcessor with the specified production
list, type, and list of parameters.
- Parameters:
production
- the list of all production rules.type
- the type description.parameters
- production description, elements can be Integer or
String types where Integer denotes a reference to another production
and String represents a regular expression.
ProductionProcessor
public ProductionProcessor(boolean casesensitive,
ProductionProcessor[] production,
java.lang.String type,
java.lang.Object[] parameters)
throws java.lang.Exception
- Constructs a new ProductionProcessor with the specified production
list, type, and list of parameters.
- Parameters:
casesensitive
- case sensitivity of parser.production
- the list of all production rules.type
- the type description.parameters
- production description, elements can be Integer or
String types where Integer denotes a reference to another production
and String represents a regular expression.
ProductionProcessor
public ProductionProcessor(java.lang.reflect.Method codeGen,
boolean casesensitive,
ProductionProcessor[] production,
java.lang.String type,
java.lang.Object[] parameters)
throws java.lang.Exception
- Constructs a new ProductionProcessor with the specified production
list, type, and list of parameters.
- Parameters:
codeGen
- a function used for automatic code generation.casesensitive
- case sensitivity of parser.production
- the list of all production rules.type
- the type description.parameters
- production description, elements can be Integer or
String types where Integer denotes a reference to another production
and String represents a regular expression.
initializeProcessors
public void initializeProcessors()
- Initializes usable subproduction processor array by grouping
production processors and subproduction processors. This function
must be called exactly once for each production immediately after all
productions are defined (this provides dynamic referencing).
beginningMatches
public RETree beginningMatches(java.lang.String input)
throws java.lang.Exception
- Returns a tree if the beginning of the specified string is matched,
otherwise returns null.
- Overrides:
beginningMatches
in class SubProductionProcessor
- Parameters:
input
- the string to be tested and parsed.- Returns:
- a tree (match) or null (no match).
