Specified by:

getPrecedence in class AbstractExpression

Returns:

100

getValueType

public ValueType getValueType()

getValue

public Object getValue()

toString

public void toString(StringBuilder buf)

renders the literal as parseable XQuery. Note that

Specified by:

toString in class AbstractExpression

Parameters:

buf - the buffer to append to

escapeText

public static void escapeText(String s,
              StringBuilder buf)

Append the string to the buffer, with characters escaped appropriately for XML (and XQuery) text. The characters ", &, <, >, {, }, and \r are replaced with character entities or numeric character references.

Append the string to the buffer, escaped as in escapeText(String, StringBuilder), surrounded by double quotes (").

Parameters:

s - the appended string

buf - the buffer appended to

accept

public AbstractExpression accept(ExpressionVisitor visitor)

propEquals

public boolean propEquals(AbstractExpression other)

Overrides:

propEquals in class AbstractExpression

Parameters:

other - another expression

Returns:

whether the other expression and this one have all the same local properties

equivHash

public int equivHash()

Returns:

a hashcode that is consistent with AbstractExpression.equivalent(AbstractExpression)
