Function Documentation

closeClassFile()

void closeClassFile

(

JavaClass *

jc

)

Closes the .class file and releases resources used by the JavaClass struct.

Parameters

JavaClass*

jc - pointer to the class to be closed.

Note

This function does not free the *jc pointer.

decodeAccessFlags()

void decodeAccessFlags	(	uint16_t	flags,
		char *	buffer,
		int32_t	buffer_len,
		enum AccessFlagsType	acctype
	)

Given flags of a certain method/field/class, this class will convert the bits to a string telling which flags are set to 1, writing the result in the output buffer.

Parameters

	uint16_t	flags - the flags of the method/field/class
[out]	char*	buffer - pointer to where the string will be stored
	int32_t	buffer_len - length of the buffer
	enum	AccessFlagsType acctype - type of access flags, telling if it is a class, a method or a field.

This method will write at most buffer_len characters to the output buffer. Depending on parameter acctype, meaning for some bits might change.

decodeJavaClassStatus()

const char* decodeJavaClassStatus

(

enum JavaClassStatus

status

)

Decodes JavaClassStatus enumeration elements.

Parameters

enum	JavaClassStatus status - identifier of the enumeration to be translated.

Returns

const char* - pointer to char containing the decoded status

openClassFile()

void openClassFile	(	JavaClass *	jc,
		const char *	path
	)

Opens a class file and parse it, storing the class information in the JavaClass structure.

Parameters

JavaClass*	jc - pointer to the structure that will hold the class data
const	char* path - string containing the path to the class file to be read

This function opens the .class file and reads its content from the file by filling in the fields of the JavaClass struct. A bunch of other functions from different modules are called to read some pieces of the class file. Various checks are made during the parsing of the read data.
