public final class POJONode
Value node that contains a wrapped POJO, to be serialized as
a JSON constructed through data mapping (usually done by
calling ObjectMapper
).

asToken()
Method that can be used for efficient type detection when using stream abstraction for traversing nodes. |

equals(Object o)
Equality for node objects is defined as full (deep) value equality. |

getPojo()
Method that can be used to access the POJO this node wraps. |

getValueAsBoolean(boolean defaultValue)
Method that will try to convert value of this node to a Java boolean. |

getValueAsDouble(double defaultValue)
Method that will try to convert value of this node to a Java double. |
int |
getValueAsInt(int defaultValue)
Method that will try to convert value of this node to a Java int. |
long |
getValueAsLong(long defaultValue)
Method that will try to convert value of this node to a Java long. |
String |
getValueAsText()
Method that will return valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise null. |

isPojo()
Method that can be used to check if the node is a wrapper for a POJO ("Plain Old Java Object" aka "bean". |

instead.
