Method Detail
-
getBitString
public BitString getBitString()
- Returns:
- the underlying BitString
-
clone
public SqlBinaryStringLiteral clone(SqlParserPos pos)
Description copied from class:SqlNode
Clones a SqlNode with a different position.- Overrides:
clone
in classSqlLiteral
-
unparse
public void unparse(SqlWriter writer, int leftPrec, int rightPrec)
Description copied from class:SqlNode
Writes a SQL representation of this node to a writer.The
leftPrec
andrightPrec
parameters give us enough context to decide whether we need to enclose the expression in parentheses. For example, we need parentheses around "2 + 3" if preceded by "5 *". This is because the precedence of the "*" operator is greater than the precedence of the "+" operator.The algorithm handles left- and right-associative operators by giving them slightly different left- and right-precedence.
If
SqlWriter.isAlwaysUseParentheses()
is true, we use parentheses even when they are not required by the precedence rules.For the details of this algorithm, see
SqlCall.unparse(org.apache.calcite.sql.SqlWriter, int, int)
.- Overrides:
unparse
in classSqlLiteral
- Parameters:
writer
- Target writerleftPrec
- The precedence of theSqlNode
immediately preceding this node in a depth-first scan of the parse treerightPrec
- The precedence of theSqlNode
immediately

concat1
protected SqlAbstractStringLiteral concat1(java.util.List<SqlLiteral> literals)
Description copied from class:SqlAbstractStringLiteral
Helper routine forSqlUtil.concatenateLiterals(java.util.List<org.apache.calcite.sql.SqlLiteral>)
.- Specified by:
concat1
in classSqlAbstractStringLiteral
- Parameters:
literals
- homogeneous StringLiteral args- Returns:
- StringLiteral with concatenated value. this == lits[0], used only for method dispatch.
