Method Detail

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.

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:

next

public PropertyPath next()

Returns the next nested PropertyPath.

Returns:

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

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:

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

iterator

public Iterator<PropertyPath> iterator()

Specified by:

iterator in interface Iterable<PropertyPath>
