public abstract class Node extends java.lang.Object
Base class for all nodes.The nodes form the node-graph described in the YAML Specification.
While loading, the node graph is usually created by the
Composer
, and later transformed into application specific Java classes by the classes from theorg.yaml.snakeyaml.constructor
package.

Method Detail

getTag
public Tag getTag()
Tag of this node.Every node has a tag assigned. The tag is either local or global.
- Returns:
- Tag of this node.
-
getEndMark
public Mark getEndMark()
-
getNodeId
public abstract NodeId getNodeId()
For error reporting.- Returns:
- scalar, sequence, mapping

- "class variable 'id' in PyYAML"
-
getStartMark
public Mark getStartMark()
-
setTag
public void setTag(Tag tag)
-
equals
public final boolean equals(java.lang.Object obj)
Node is only equal to itself- Overrides:

getType
public java.lang.Class<? extends java.lang.Object> getType()
-
setType
public void setType(java.lang.Class<? extends java.lang.Object> type)
-
setTwoStepsConstruction
public void setTwoStepsConstruction(boolean twoStepsConstruction)
-
isTwoStepsConstruction
public boolean isTwoStepsConstruction()
Indicates if this node must be constructed in two steps.Two-step construction is required whenever a node is a child (direct or indirect) of it self. That is, if a recursive structure is build using anchors and aliases.
Set by
Composer
, used during the construction process.Only relevant during loading.
- Returns:
true
if the node is self referenced.
-
hashCode
public final int hashCode()
- Overrides:
hashCode
in classjava.lang.Object
-
useClassConstructor
public boolean useClassConstructor()

setUseClassConstructor
public void setUseClassConstructor(java.lang.Boolean useClassConstructor)
-
isResolved
@Deprecated public boolean isResolved()
Deprecated.Since v1.22. Absent in immediately prior versions, but present previously. Restored deprecated for backwards compatibility.Indicates if the tag was added byResolver
.- Returns:
- true if the tag of this node was resolved
