The PrefixTermEnum type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
| PrefixTermEnum | Initializes a new instance of the PrefixTermEnum class |
Methods
| Name | Description | |
|---|---|---|
| Close | Closes the enumeration to further activity, freeing resources. (Inherited from FilteredTermEnum.) | |
| Difference | (Overrides FilteredTermEnum..::..Difference()()()().) | |
| DocFreq | Returns the docFreq of the current Term in the enumeration.
Returns -1 if no Term matches or all terms have been enumerated.
(Inherited from FilteredTermEnum.) | |
| EndEnum | (Overrides FilteredTermEnum..::..EndEnum()()()().) | |
| Equals | (Inherited from Object.) | |
| Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) | |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
| GetPrefixTerm | ||
| GetType | Gets the Type of the current instance. (Inherited from Object.) | |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
| Next | Increments the enumeration to the next element. True if one exists. (Inherited from FilteredTermEnum.) | |
| SetEnum | use this method to set the actual TermEnum (e.g. in ctor),
it will be automatically positioned on the first matching term.
(Inherited from FilteredTermEnum.) | |
| SkipTo | Obsolete. Skips terms to the first beyond the current whose value is
greater or equal to target. Returns true iff there is such
an entry. Behaves as if written: (Inherited from TermEnum.)
public boolean skipTo(Term target) {
do {
if (!next())
return false;
} while (target > term());
return true;
}
Some implementations *could* be considerably more efficient than a linear scan.
Check the implementation to be sure.

| Term | Returns the current Term in the enumeration.
Returns null if no Term matches or all terms have been enumerated.

| TermCompare | (Overrides FilteredTermEnum..::..TermCompare(Term).) | |
| ToString | (Inherited from Object.) |
Fields
| Name | Description | |
