Function Documentation

decodeTag()

const char* decodeTag

(

uint8_t

tag

)

Decodes ConstantPoolTag enumeration elements.

Parameters

uint8_t

tag - identifier of the enumeration to be translated.

Returns

const char* - pointer to char containing the decoded tag

printConstantPool()

void printConstantPool

(

JavaClass *

jc

)

Function to print all the constants from the constant pool of the class file.

Parameters

JavaClass

*jc - pointer to JavaClass structure that must already be loaded

readConstantPoolEntry()

char readConstantPoolEntry	(	JavaClass *	jc,
		cp_info *	entry
	)

Reads a cp_info from the file.

This function identifies the structure indicated by the tag byte and selects the corresponding reading type

Parameters

JavaClass*	jc - pointer to the structure to be read.
cp_info*	entry - where the data read is written

Returns

char - retuns 0 if something unexpected happened or failure, 1 in case of success
