Method Detail

binaryNameToFieldDescriptor

public static @FieldDescriptor String binaryNameToFieldDescriptor(@BinaryName String classname)

Deprecated.

Convert a binary name to a field descriptor. For example, convert "java.lang.Object[]" to "[Ljava/lang/Object;" or "int" to "I" or "pkg.Outer$Inner" to "Lpkg/Outer$Inner;".

There are no binary names for primitives or array types. Nonetheless, this method works for them. It converts "java.lang.Object[]" to "[Ljava/lang/Object;" or "int" to "I".

Parameters:

classname - name of the class, in binary class name format

Returns:

name of the class, in field descriptor format

primitiveTypeNameToFieldDescriptor

public static @FieldDescriptor String primitiveTypeNameToFieldDescriptor(String primitiveName)

Deprecated.

Convert a primitive Java type name (e.g., "int", "double", etc.) to a field descriptor (e.g., "I", "D", etc.).

Parameters:

primitiveName - name of the type, in Java format

Returns:

name of the type, in field descriptor format

Throws:

IllegalArgumentException - if primitiveName is not a valid primitive type name

binaryNameToClassGetName

public static @ClassGetName String binaryNameToClassGetName(String bn)

Deprecated.

Convert from a BinaryName to the format of Class.getName().

There are no binary names for primitives or array types. Nonetheless, this method works for them. It converts "java.lang.Object[]" to "[Ljava.lang.Object;" or "int" to "int".

Parameters:

bn - the binary name to convert

Returns:

the class name, in Class.getName format

fieldDescriptorToClassGetName

public static @ClassGetName String fieldDescriptorToClassGetName(String fd)

Deprecated.

Convert from a FieldDescriptor to the format of Class.getName().

Parameters:

fd - the class, in field descriptor format

Returns:

the class name, in Class.getName format

arglistToJvm

public static String arglistToJvm(String arglist)

Deprecated.

Convert a fully-qualified argument list from Java format to JVML format. For example, convert "(java.lang.Integer[], int, java.lang.Integer[][])" to "([Ljava/lang/Integer;I[[Ljava/lang/Integer;)".

Parameters:

arglist - an argument list, in Java format

Returns:

argument list, in JVML format

fieldDescriptorToBinaryName

public static @BinaryName String fieldDescriptorToBinaryName(String classname)

Deprecated.

Convert a field descriptor to a binary name. For example, convert "[Ljava/lang/Object;" to "java.lang.Object[]" or "I" to "int".

Parameters:

classname - name of the type, in JVML format

Returns:

name of the type, in Java format

arglistFromJvm

public static String arglistFromJvm(String arglist)

Deprecated.

Convert an argument list from JVML format to Java format. For example, convert "([Ljava/lang/Integer;I[[Ljava/lang/Integer;)" to "(java.lang.Integer[], int, java.lang.Integer[][])".

Parameters:

arglist - an argument list, in JVML format

Returns:

argument list, in Java format
