Constructor Details

StructDeclaration

public StructDeclaration(List<StructDeclaration.Member> members,
 Optional<Pair<Token,Token>> boundary)

Method Details

anonMember

public static StructDeclaration.Member anonMember(Expression expression)

Returns:

an anonymous attribute declaration wrapping the given expression.

jsonStyleMember

public static StructDeclaration.Member jsonStyleMember(Token ident,
 Expression expression)

Returns a json style (foo: bar) struct member

jsonStyleMember

public static StructDeclaration.Member jsonStyleMember(String ident,
 Expression expression)

Returns a json style (foo: bar) struct member

sqlStyleMember

public static StructDeclaration.Member sqlStyleMember(Token ident,
 Expression expression,
 Token as)

Returns an sql style (bar as foo) struct member

selectAllMember

public static StructDeclaration.Member selectAllMember(Token asterisk)

Returns a select-all ({*}) struct member

appendSource

protected void appendSource(StringBuilder appendTo)

Implementers extend this to append their source to the given string builder. Done via string builder to encourage a more efficient implementation than is possible with concatenating multiple toString calls that typically contruct a string builder anyway.

accept

public <T,
R> R accept(ExpressionVisitor<T,R> visitor,
 T data)

getMember

public StructDeclaration.Member getMember(int index)

Shortcut for getMembers().get(index)

Returns:

the AttrDeclaration at the given zero-based index

Throws:

IndexOutOfBoundsException - if the index is < 0 or > size

withNewMembers

public StructDeclaration withNewMembers(List<StructDeclaration.Member> newMembers,
 Optional<Pair<Token,Token>> newBoundary)

equals

public boolean equals(Object o)

canEqual

protected boolean canEqual(Object other)

hashCode

public int hashCode()

getMembers

public List<StructDeclaration.Member> getMembers()

getBoundary

public Optional<Pair<Token,Token>> getBoundary()

Returns:

a pair of tokens that represent the start and end of this expression, to be used when giving users information about where errors have occurred. If the expression has been rebuilt then the boundary may be empty or it may be from the original expression. Intended for use in problems to trace errors back to their source.

toString

public final String toString()

Overrides:

toString in class Object

Returns:

the source, surrounded by the class name to make it easier to discern from a plane string among other debug output

toSource

public final String toSource()

Specified by:

toSource in interface Expression

Returns:

a normalized version of the AST that can be parsed to be exactly the same AST as this
