Parameters:   interfaceMethodType - the type descriptor of the method beingreferenced. public  int getMethodRefEntry(String methodClassName, String methodName, String methodType)      Get the index of a given CONSTANT_METHODREF entry in the constant pool. Parameters:   methodClassName - the name of the class which contains themethod being referenced. Parameters:   methodName - the name of the method being referenced. Parameters:   methodType - the type descriptor of the method being referenced. public  int getNameAndTypeEntry(String name, String type)      Get the index of a given CONSTANT_NAMEANDTYPE entry in the constant pool. public  int getUTF8Entry(String value)      Get the index of a given UTF8 constant pool entry. Parameters:   value - the string value of the UTF8 entry. public  void read(DataInputStream classStream)      Read the constant pool from a class input stream. public  void resolve()      Resolve the entries in the constant pool. public  int size()      Get the size of the constant pool. public  String toString()      Dump the constant pool to a string. Constructor Detail ConstantPool public ConstantPool()(Code) Initialise the constant pool. Method Detail addEntry public int addEntry(ConstantPoolEntry entry)(Code) Add an entry to the constant pool. Parameters:   entry - the new entry to be added to the constant pool. the index into the constant pool at which the entry isstored. getClassEntry public int getClassEntry(String className)(Code) Get the index of a given CONSTANT_CLASS entry in the constant pool. Parameters:   className - the name of the class for which the class entryindex is required. the index at which the given class entry occurs in theconstant pool or -1 if the value does not occur. getConstantEntry public int getConstantEntry(Object constantValue)(Code) Get the index of a given constant value entry in the constant pool. Parameters:   constantValue - the constant value for which the index isrequired. the index at which the given value entry occurs in theconstant pool or -1 if the value does not occur. getEntry public ConstantPoolEntry getEntry(int index)(Code) Get an constant pool entry at a particular index. Parameters:   index - the index into the constant pool. the constant pool entry at that index. getFieldRefEntry public int getFieldRefEntry(String fieldClassName, String fieldName, String fieldType)(Code) Get the index of a given CONSTANT_FIELDREF entry in the constant pool. Parameters:   fieldClassName - the name of the class which contains the fieldbeing referenced. Parameters:   fieldName - the name of the field being referenced. Parameters:   fieldType - the type descriptor of the field being referenced. the index at which the given field ref entry occurs in theconstant pool or -1 if the value does not occur. getInterfaceMethodRefEntry public int getInterfaceMethodRefEntry(String interfaceMethodClassName, String interfaceMethodName, String interfaceMethodType)(Code) Get the index of a given CONSTANT_INTERFACEMETHODREF entry in the constant pool. Parameters:   interfaceMethodClassName - the name of the interface whichcontains the method being referenced. Parameters:   interfaceMethodName - the name of the method being referenced. Parameters:   interfaceMethodType - the type descriptor of the method beingreferenced. the index at which the given method ref entry occurs in theconstant pool or -1 if the value does not occur. getMethodRefEntry public int getMethodRefEntry(String methodClassName, String methodName, String methodType)(Code) Get the index of a given CONSTANT_METHODREF entry in the constant pool. Parameters:   methodClassName - the name of the class which contains themethod being referenced. Parameters:   methodName - the name of the method being referenced. Parameters:   methodType - the type descriptor of the method being referenced. the index at which the given method ref entry occurs in theconstant pool or -1 if the value does not occur. getNameAndTypeEntry public int getNameAndTypeEntry(String name, String type)(Code) Get the index of a given CONSTANT_NAMEANDTYPE entry in the constant pool.
