Constructor Detail

DynamicBitFieldInstantiation

public DynamicBitFieldInstantiation(AstLocation location,
                                    TypeReference typeReference,
                                    Expression lengthExpression)

Constructor.

Parameters:

location - AST node location.

typeReference - Reference to the instantiated type definition.

lengthExpression - Length expression associated with this dynamic bit field type.

Method Detail

visitChildren

public void visitChildren(ZserioAstVisitor visitor)

Description copied from interface: AstNode

Visit children of the current AST node using given visitor.

Specified by:

visitChildren in interface AstNode

Overrides:

visitChildren in class TypeInstantiation

Parameters:

visitor - Visitor to use.

getLengthExpression

public Expression getLengthExpression()

Gets the expression which gives dynamic bit field length. Length expression must be provided according to the grammar, so this method cannot return null.

Returns:

Length expression.

getMaxBitSize

public int getMaxBitSize()

Gets the maximal number of bits used by this dynamic bit field.

Returns:

Maximal number of bits used by this dynamic bit field.

getUpperBound

public java.math.BigInteger getUpperBound()

Gets upper bound for this integer type.

Returns:

Upper bound.

getLowerBound

public java.math.BigInteger getLowerBound()

Gets lower bound for this integer type.

Returns:

Lower bound.

getBaseType

public DynamicBitFieldType getBaseType()

Description copied from class: TypeInstantiation

Gets base type - i.e. the type got by resolving subtypes.

Overrides:

getBaseType in class TypeInstantiation

Returns:

Zserio base type.
