ExtensionOccurrenceFilter

public ExtensionOccurrenceFilter()

Method Detail

getCount

public int getCount(String extension)

Get occurrences of given extension.

The given extension should not contain a leading '.' character.

Parameters:

extension -

Returns:

occurrence count

getExtensions

public String[] getExtensions()

Get file extension encountered. The returned string will not contain a leading '.' character

Returns:

non-null but possibly empty array of file extensions

getOccurrences

public Map<String,ExtensionOccurrence> getOccurrences()

Get map of extensions to occurrence counts. The extensions contained in the returned map will not include a leading '.' character.

Returns:

non-null but possibly empty map

reset

public BaseTreeFilter reset()

Description copied from class: BaseTreeFilter

Reset the filter. Sub-classes may override.

Overrides:

reset in class BaseTreeFilter

Returns:

this tree filter

include

public boolean include(org.eclipse.jgit.treewalk.TreeWalk walker)
                throws IOException

Specified by:

include in class org.eclipse.jgit.treewalk.filter.TreeFilter

Throws:

IOException

clone

public org.eclipse.jgit.treewalk.filter.TreeFilter clone()

Description copied from class: BaseTreeFilter

Clones the tree filter.

The default implementation throws a UnsupportedOperationException and sub-classes should override if filter cloning is supported.

Overrides:

clone in class BaseTreeFilter
