Method Detail

properties

java.util.Map<ELEMENT_IDENTIFIER,java.util.Map<java.lang.String,PROPERTY_SCHEMA>> properties()

filter

SELF filter(java.util.Set<ELEMENT_IDENTIFIER> elementIdentifieresToKeep)

union

SELF union(SELF other)

allProperties

@Derived
default java.util.Set<java.lang.String> allProperties()

hasProperties

@Derived
default boolean hasProperties()

hasProperties

@Default
default boolean hasProperties(ELEMENT_IDENTIFIER elementIdentifier)

propertySchemasFor

@Default
default java.util.List<PROPERTY_SCHEMA> propertySchemasFor(ELEMENT_IDENTIFIER elementIdentifier)

toMap

@Derived
default java.util.Map<java.lang.String,java.lang.Object> toMap()

filterProperties

@Derived
default java.util.Map<ELEMENT_IDENTIFIER,java.util.Map<java.lang.String,PROPERTY_SCHEMA>> filterProperties(java.util.Set<ELEMENT_IDENTIFIER> identifiersToKeep)

unionProperties

@Lazy
default java.util.Map<java.lang.String,PROPERTY_SCHEMA> unionProperties()

Returns a union of all properties in the given schema. If a property with the same key exists for more then one label, this method makes sure they have the same type.

unionSchema

default java.util.Map<ELEMENT_IDENTIFIER,java.util.Map<java.lang.String,PROPERTY_SCHEMA>> unionSchema(java.util.Map<ELEMENT_IDENTIFIER,java.util.Map<java.lang.String,PROPERTY_SCHEMA>> rightProperties)
