Method Detail

toDotPath

String toDotPath()

Returns the dot based path notation using PersistentProperty.getName().

Returns:

toDotPath

String toDotPath(Converter<? super T,String> converter)

Returns the dot based path notation using the given Converter to translate individual PersistentPropertys to path segments.

Parameters:

converter -

Returns:

toPath

String toPath(String delimiter)

Returns a String path with the given delimiter based on the PersistentProperty.getName().

Parameters:

delimiter - will default to . if null is given.

Returns:

toPath

String toPath(String delimiter,
            Converter<? super T,String> converter)

Returns a String path with the given delimiter using the given Converter for PersistentProperty to String conversion.

Parameters:

delimiter - will default to . if null is given.

converter - will default to use PersistentProperty.getName().

Returns:

getLeafProperty

T getLeafProperty()

Returns the last property in the PersistentPropertyPath. So for foo.bar it will return the PersistentProperty for bar. For a simple foo it returns PersistentProperty for foo.

Returns:

getBaseProperty

T getBaseProperty()

Returns the first property in the PersistentPropertyPath. So for foo.bar it will return the PersistentProperty for foo. For a simple foo it returns PersistentProperty for foo.

Returns:

isBasePathOf

boolean isBasePathOf(PersistentPropertyPath<T> path)

Returns whether the given PersistentPropertyPath is a base path of the current one. This means that the current PersistentPropertyPath is basically an extension of the given one.

Parameters:

path -

Returns:

getExtensionForBaseOf

PersistentPropertyPath<T> getExtensionForBaseOf(PersistentPropertyPath<T> base)

Returns the sub-path of the current one as if it was based on the given base path. So for a current path foo.bar and a given base foo it would return bar. If the given path is not a base of the the current one the current PersistentPropertyPath will be returned as is.

Parameters:

base -

Returns:

getParentPath

PersistentPropertyPath<T> getParentPath()

Returns the parent path of the current PersistentPropertyPath, i.e. the path without the leaf property. This happens up to the base property. So for a direct property reference calling this method will result in returning the property.

Returns:

getLength

int getLength()

Returns the length of the PersistentPropertyPath.

Returns:
