Example 1 with BigintType

use of io.trino.spi.type.BigintType in project trino by trinodb.

the class JoinCompiler method generateHashPositionMethod.

    Variable thisVariable = hashPositionMethod.getThis();
    BytecodeExpression hashChannel = thisVariable.getField(hashChannelField);
    BytecodeExpression bigintType = constantType(callSiteBinder, BigintType.BIGINT);
