Method Details

getOwningType

public TypeInformation<?> getOwningType()

Returns the owning type of the PropertyPath.

Returns:

the owningType will never be null.

getSegment

public String getSegment()

Returns the name of the PropertyPath.

Returns:

the name will never be null.

getLeafProperty

public PropertyPath getLeafProperty()

Returns the leaf property of the PropertyPath.

Returns:

will never be null.

getLeafType

public Class<?> getLeafType()

Returns the type of the leaf property of the current PropertyPath.

Returns:

will never be null.

getType

public Class<?> getType()

Returns the type of the property will return the plain resolved type for simple properties, the component type for any Iterable or the value type of a Map if the property is one.

Returns:

getTypeInformation

public TypeInformation<?> getTypeInformation()

next

@Nullable
public PropertyPath next()

Returns the next nested PropertyPath.

Returns:

the next nested PropertyPath or null if no nested PropertyPath available.

See Also:

• hasNext()

hasNext

public boolean hasNext()

Returns whether there is a nested PropertyPath. If this returns true you can expect next() to return a non- null value.

Returns:

toDotPath

public String toDotPath()

Returns the PropertyPath in dot notation.

Returns:

isCollection

public boolean isCollection()

Returns whether the PropertyPath is actually a collection.

Returns:

nested

public PropertyPath nested(String path)

Returns the PropertyPath for the path nested under the current property.

Parameters:

path - must not be null or empty.

Returns:

will never be null.

iterator

public Iterator<PropertyPath> iterator()

Specified by:

iterator in interface Iterable<PropertyPath>

equals

public boolean equals(@Nullable
 Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

from

type -

Returns:

from

public static PropertyPath from(String source,
 TypeInformation<?> type)

Extracts the PropertyPath chain from the given source String and TypeInformation.
Uses SPLITTER by default and SPLITTER_FOR_QUOTED for quoted literals.

Parameters:
