  - name
```
StringOperand<String> name()
```
    Returns an operand to build predicates for the name part of variables.
    
    Returns:
    
    the variable-name-specific predicate operand
  - undefined
```
Predicate undefined(String variableName)
```
    Returns an undefined variable predicate.
    
    Parameters:
    
    variableName - the variable name
    
    Returns:
    
    the new predicate instance
  - undefined
```
Predicate undefined(ValueAccessor<?> variableAccessor)
```
    Returns undefined variable predicate.
    
    Parameters:
    
    variableAccessor - the variable accessor
    
    Returns:
    
    the new predicate instance
  - stringValue
```
StringOperand<String> stringValue()
```
    Returns an operand to build predicates for the value part of variables.
    
    The operand is specific to string values.
    
    Returns:
    
    the value-specific predicate operand
  - timestampValue
```
TimestampOperand<Instant> timestampValue()
```
    Returns an operand to build predicates for the value part of variables.
    
    The operand is specific to timestamp values.
    
    Returns:
    
    the value-specific predicate operand
  - booleanValue
```
BooleanOperand<Boolean> booleanValue()
```
    Returns an operand to build predicates for the value part of variables.
    
    The operand is specific to boolean values.
    
    Returns:
    
    the value-specific predicate operand
  - longValue
```
NumberOperand<Long> longValue()
```
    Returns an operand to build predicates for the value part of variables.
    
    The operand is specific to long values.
    
    Returns:
    
    the value-specific predicate operand
  - doubleValue
```
NumberOperand<Double> doubleValue()
```
    Returns an operand to build predicates for the value part of variables.
    
    The operand is specific to double values.
    
    Returns:
    
    the value-specific predicate operand
  - valueIsNull
```
Predicate valueIsNull()
```
    Returns a predicate to check that the variable value is null, irrespective of the value type.
    
    NOTE
    
    Do not use this predicate with Predicate.not() method. Use valueIsNotNull() instead.
    
    Returns:
    
    the new predicate instance
  - valueIsNotNull
```
Predicate valueIsNotNull()
```
    Returns a predicate to check that the variable value is null, irrespective of the value type.
    
    NOTE
    
    Do not use this predicate with Predicate.not() method. Use valueIsNull() instead. *
    
    Returns:
    
    the new predicate instance
  - nameAndValueEq
```
<V> Predicate nameAndValueEq(ValueAccessor<V> valueAccessor,
                             V expectedValue)
```
    Returns a predicate to check for variables with the given name and value.
    
    Type Parameters:
    
    V - the type of the variable value
    
    Parameters:
    
    valueAccessor - the expected variable accessor
    
    expectedValue - the expected variable value
    
    Returns:
    
    the new predicate instance
  - nameAndValueEq
```
Predicate nameAndValueEq(String expectedName,
                         Object expectedValue)
```
    Returns a predicate to check for variables with the given name and value.
    
    Parameters:
    
    expectedName - the expected variable name
    
    expectedValue - the expected variable value
    
    Returns:
    
    the new predicate instance
