Constructor Detail

TryTypeInfo

public TryTypeInfo(TypeInformation<A> elemTypeInfo)

Method Detail

elemTypeInfo

public TypeInformation<A> elemTypeInfo()

isBasicType

public boolean isBasicType()

Description copied from class: TypeInformation

Checks if this type information represents a basic type. Basic types are defined in BasicTypeInfo and are primitives, their boxing types, Strings, Date, Void, ...

Specified by:

isBasicType in class TypeInformation<T extends scala.util.Try<A>>

Returns:

True, if this type information describes a basic type, false otherwise.

isTupleType

public boolean isTupleType()

Description copied from class: TypeInformation

Checks if this type information represents a Tuple type. Tuple types are subclasses of the Java API tuples.

Specified by:

isTupleType in class TypeInformation<T extends scala.util.Try<A>>

Returns:

True, if this type information describes a tuple type, false otherwise.

isKeyType

public boolean isKeyType()

Description copied from class: TypeInformation

Checks whether this type can be used as a key. As a bare minimum, types have to be hashable and comparable to be keys.

Specified by:

isKeyType in class TypeInformation<T extends scala.util.Try<A>>

Returns:

True, if the type can be used as a key, false otherwise.

getTotalFields

public int getTotalFields()

Description copied from class: TypeInformation

Gets the number of logical fields in this type. This includes its nested and transitively nested fields, in the case of composite types. In the example below, the OuterType type has three fields in total.

Specified by:

getTotalFields in class TypeInformation<T extends scala.util.Try<A>>

Returns:

The number of fields in this type, including its sub-fields (for composite types)

getArity

public int getArity()

Description copied from class: TypeInformation

Gets the arity of this type - the number of fields without nesting.

Specified by:

getArity in class TypeInformation<T extends scala.util.Try<A>>

Returns:

Gets the number of fields in this type without nesting.

getTypeClass

public Class<T> getTypeClass()

Description copied from class: TypeInformation

Gets the class of the type represented by this type information.

Specified by:

getTypeClass in class TypeInformation<T extends scala.util.Try<A>>

Returns:

The class of the type represented by this type information.

getGenericParameters

public List<TypeInformation<?>> getGenericParameters()

Description copied from class: TypeInformation

Returns the generic parameters of this type.

Overrides:

getGenericParameters in class TypeInformation<T extends scala.util.Try<A>>

Returns:

The list of generic parameters. This list can be empty.

createSerializer

public TypeSerializer<T> createSerializer(ExecutionConfig executionConfig)

Description copied from class: TypeInformation

Creates a serializer for the type. The serializer may use the ExecutionConfig for parameterization.

Specified by:

createSerializer in class TypeInformation<T extends scala.util.Try<A>>

Parameters:

executionConfig - The config used to parameterize the serializer.

Returns:

A serializer for this type.

equals

public boolean equals(Object obj)

Specified by:

equals in class TypeInformation<T extends scala.util.Try<A>>

canEqual

public boolean canEqual(Object obj)

Description copied from class: TypeInformation

Returns true if the given object can be equaled with this object. If not, it returns false.

Specified by:

canEqual in class TypeInformation<T extends scala.util.Try<A>>

Parameters:

obj - Object which wants to take part in the equality relation

Returns:

true if obj can be equaled with this, otherwise false

hashCode

public int hashCode()

Specified by:

hashCode in class TypeInformation<T extends scala.util.Try<A>>

toString

public String toString()

Specified by:

toString in class TypeInformation<T extends scala.util.Try<A>>
