class AbstractMethod[source]

AbstractMethod(tokens:Union[str, List[str]], delimiter:str=' ')

Creates an AbstractMethod from the given tokens, which can be either:

• a string with tokens delimited by delimiter (defaults to a single space)
• a list of tokens

Note that empty tokens are ignored.

method1 = AbstractMethod("private static int METHOD_1 ( ) { return 0 ; }")
method1

private static int METHOD_1 ( ) { return 0 ; }

method2 = AbstractMethod(["public", "double", "METHOD_1", "(", "double", "VAR_1", ")", "{", "return", "VAR_1", ";", "}"])
method2

public double METHOD_1 ( double VAR_1 ) { return VAR_1 ; }

Interact with Edit Operations

AbstractMethod.getEditDistanceTo[source]

AbstractMethod.getEditDistanceTo(other:AbstractMethod)

Returns the Levenshtein edit distance to the AbstractMethod given by other.

method1.getEditDistanceTo(method2)

6

AbstractMethod.getEditOperationsTo[source]

AbstractMethod.getEditOperationsTo(other:AbstractMethod)

Returns the minimal list of basic edit operations (no CompoundOperations), which if applied, would result in the AbstractMethod given by other. The length of the returned list is the Levenshtein distance to other.

method1 = AbstractMethod("private static int METHOD_1 ( ) { return 0 ; }")
method2 = AbstractMethod("public double METHOD_1 ( double VAR_1 ) { return VAR_1 ; }")

operations = method1.getEditOperationsTo(method2)

operations

[DELETE 0,
 REPLACE 0 -> 'public',
 REPLACE 1 -> 'double',
 INSERT 4 -> 'double',
 INSERT 5 -> 'VAR_1',
 REPLACE 9 -> 'VAR_1']

AbstractMethod.applyEditOperation[source]

AbstractMethod.applyEditOperation(operation:Union[InsertOperation, DeleteOperation, ReplaceOperation, CompoundOperation])

Applies the given operation.

Note: This changes the original AbstractMethod, so you should make a copy if you want to keep the original.

AbstractMethod.applyEditOperations[source]

AbstractMethod.applyEditOperations(operations:List[Union[InsertOperation, DeleteOperation, ReplaceOperation, CompoundOperation]])

Applies the given list of operations in order.

Note: This changes the original AbstractMethod, so you should make a copy if you want to keep the original.

method1 = AbstractMethod("private static int METHOD_1 ( ) { return 0 ; }")
method2 = AbstractMethod("public double METHOD_1 ( double VAR_1 ) { return VAR_1 ; }")

operations = method1.getEditOperationsTo(method2)
method1.applyEditOperations(operations)

method1

public double METHOD_1 ( double VAR_1 ) { return VAR_1 ; }

method2

public double METHOD_1 ( double VAR_1 ) { return VAR_1 ; }

method1 == method2

True
