Parameters:

allowDuplicateKeys - false to reject duplicate mapping keys

public boolean isWrappedToRootException()

setWrappedToRootException

public void setWrappedToRootException(boolean wrappedToRootException)

Wrap runtime exception to YAMLException during parsing or leave them as they are Default is to leave original exceptions

Parameters:

wrappedToRootException - - true to convert runtime exception to YAMLException

getMaxAliasesForCollections

public int getMaxAliasesForCollections()

setMaxAliasesForCollections

public void setMaxAliasesForCollections(int maxAliasesForCollections)

Restrict the amount of aliases for collections (sequences and mappings) to avoid https://en.wikipedia.org/wiki/Billion_laughs_attack

Parameters:

maxAliasesForCollections - set max allowed value (50 by default)

setAllowRecursiveKeys

public void setAllowRecursiveKeys(boolean allowRecursiveKeys)

Allow recursive keys for mappings. By default it is not allowed. This setting only prevents the case when the key is the value. If the key is only a part of the value (the value is a sequence or a mapping) then this case is not recognized and always allowed.

Parameters:

allowRecursiveKeys - - false to disable recursive keys

getAllowRecursiveKeys

public boolean getAllowRecursiveKeys()
