Example 1 with ReplacedStepTree

use of org.umlg.sqlg.sql.parse.ReplacedStepTree in project sqlg by pietermartin.

the class SqlgVertexStep method addReplacedStep.

@Override
public ReplacedStepTree.TreeNode addReplacedStep(ReplacedStep replacedStep) {
    replacedStep.setDepth(this.replacedSteps.size());
    this.replacedSteps.add(replacedStep);
    if (this.replacedStepTree == null) {

    } else {

    }
    return this.replacedStepTree.getCurrentTreeNodeNode();
}

Example 2 with ReplacedStepTree

use of org.umlg.sqlg.sql.parse.ReplacedStepTree in project sqlg by pietermartin.

the class SqlgGraphStep method addReplacedStep.

@Override
public ReplacedStepTree.TreeNode addReplacedStep(ReplacedStep<?, ?> replacedStep) {
    // depth is + 1 because there is always a root node who's depth is 0
    replacedStep.setDepth(this.replacedSteps.size());
    this.replacedSteps.add(replacedStep);
    // New way of interpreting steps
    if (this.replacedStepTree == null) {
        // the first root node
        this.replacedStepTree = new ReplacedStepTree(replacedStep);
    } else {
        this.replacedStepTree.addReplacedStep(replacedStep);
    }
    return this.replacedStepTree.getCurrentTreeNodeNode();
