public VariableOperandImpl()

Method Detail

name

public StringOperand<String> name()

Description copied from interface: VariableOperand

Returns an operand to build predicates for the name part of variables.

Specified by:

name in interface VariableOperand

Returns:

the variable-name-specific predicate operand

undefined

public Predicate undefined(String variableName)

Description copied from interface: VariableOperand

Returns an undefined variable predicate.

Specified by:

undefined in interface VariableOperand

Parameters:

variableName - the variable name

Returns:

the new predicate instance

undefined

public Predicate undefined(ValueAccessor<?> variableName)

Description copied from interface: VariableOperand

Returns undefined variable predicate.

Specified by:

undefined in interface VariableOperand

Parameters:

variableName - the variable accessor

Returns:

the new predicate instance

stringValue

public StringOperand<String> stringValue()

Description copied from interface: VariableOperand

Returns an operand to build predicates for the value part of variables.

The operand is specific to string values.

Specified by:

stringValue in interface VariableOperand

Returns:

the value-specific predicate operand

timestampValue

public TimestampOperand<Instant> timestampValue()

Description copied from interface: VariableOperand

Returns an operand to build predicates for the value part of variables.

The operand is specific to timestamp values.

Specified by:

timestampValue in interface VariableOperand

Returns:

the value-specific predicate operand

booleanValue

public BooleanOperand<Boolean> booleanValue()

Description copied from interface: VariableOperand

Returns an operand to build predicates for the value part of variables.

The operand is specific to boolean values.

Specified by:

booleanValue in interface VariableOperand

Returns:

the value-specific predicate operand

longValue

public NumberOperand<Long> longValue()

Description copied from interface: VariableOperand

Returns:

the new predicate instance

valueIsNotNull

public Predicate valueIsNotNull()

Description copied from interface: VariableOperand

Returns a predicate to check that the variable value is null, irrespective of the value type.
